Infinite Horizon
Apropos of nothing save my annoyance, I did a little research on the "infinite-horizon" modeling today. "Infinite horizon" projections are where we get numbers like Social Security's supposed $11 trillion deficit. It's a way of forecasting costs off into the great beyond. It's also a load of crap. President Bush's tax cuts, if judged via an infinite horizon projection, would cost us $20 trillion, and his Medicare plan would be coming to your house to eat your children.
But the infinite horizon is BS. While trawling around the internets to figure out exactly how it works, I found a good Fact-Check.org article explaining that, well, it doesn't. Because it's so inaccurate, it was never included until the 2003 Trustees Report, which apparently was when the Bush administration decided to add fangs and a pitchfork to the Social Security numbers. A technical panel advising them on the inclusion on the number said it's misleading as a dollar estimate and should instead be expressed as a percentage of the taxable payroll numbers, which, in 2003, would have been 3.8%. Not so impressive, is it?
It gets worse. In a letter to the Social Security Advising Board, the American Academy of Actuaries (nominated for most boring national convention six years in a row!) wrote:
The new measures of the unfunded obligations included in the 2003 report provide little if any useful information about the program’s long-range finances and indeed are likely to mislead anyone lacking technical expertise in the demographic, economic, and actuarial aspects of the program’s finances into believing that the program is in far worse financial condition than is actually indicated.
...
Thus, we believe that including these values in the Trustees Report is unnecessary and is, on balance, a detriment to the Trustees’ charge to provide a meaningful and balanced presentation of the financial status of the program.
So the whole thing is useless. What's really aggravating is that Bush has shown no compunction about shortening every projection we've got. Bush has rejected 10-year budgetary outlooks in favor of five-year projections, and the Medicare expansion was regularly undersold and placed on a shortened projection in order to lowball the costs. And that's not even getting into the the intimidation of its chief actuary, who believed it'd cost $100 billion more than the Administration was admitting, and was told he'd lose his job if he said anything. He was right.
This, I feel, has been the media's primary failure over the past few few years. By not insisting on any numerical standard for their economic reporting, they've allowed the Administration to bewilder voters by placing every policy on a different projection depending on whether they want it to look healthy or near-death. That failure has denied news consumers any sort of comparative ability when evaluating different stories. It's straight insane that voters think Social Security is in worse shape, yet they do. And, after all, how can they compare them accurately when Social Security is evaluated into the ever-stretching future and Medicare is capped at 10 years? They can't -- there's no way to decipher that. It's the media's job to provide the translation. And they've failed.

As far as the infinite horizon goes, I would think any projection that is made for a length of time longer than the planet is supposed to last would be faulty from the get go. But that's just me.

in regards to the last paragraph, this probably has something to do with the fact that the vast majority of journalists have no economic training/background at all. So they just parrot the numbers that the white house feeds them, and then maybe talk about gas prices. And then they'll invite Paul Krugman and Donald Luskin on, and let them debate as if the two were equally trustworthy.

If PV of SS deficits taken to infinity are compared to PV of GDP taken to infinity - which IS done by the Trustee's report, I'm fine with this ratio. And the ratio did not change at all from the '04 to '05 report. So the conclusion should be there was no change in the solvency issue. See - fair and really easy. But did our press report this? No, but Brad DeLong and Max Sawicky did.

Sorry for the multiple posts - not my fault though.

Why don't Democrats use this to mock Republicans. Use the infinite model to calculate how much SS will cost between 4050 and 4100. Ask Republicans if they agree with that prediction. Ask them details about it. How many workers will there be per retiree? How much will a retiree get in 2005 dollars? Will that cover the toll lanes on the commute from Mars to Venus? Economists can't predict what is going to happen next year, much less 75 years from now. Its a joke and we need to start mocking it.

I think you may be giving the press too much slack here. It's not that they aren't trained in economics, but that they just aren't that bright to begin with. They are easily bamboozled on any number of topics. We keep thinking they are the best and the brightest when in fact they be the worst and the dimmest.
